Various specimens, captured in different parts of theBritish coast by Col. Montagu and Dr. Leach, are con-tained in the British Museum. Mr. Robertson has sent it to us from Cumbray, andthe Rev. A. M. Norman from the coasts of Durham andN or th u m b e r Ian d. It has also been taken at Port Patrick and Dundrum,Ireland, by the late Mr. W. Thompson. Mr. W. found this species among trawl refuse of fishingboats, also in the stomach of fish at Falmouth. It iscommon among weeds all round the coasts of Europe. c c i^ 388 ISOPODA. NORMALIA. IDOTEID^.
